An air conditioner 131 may be installed in the center fascia 124. Theair conditioner 131 may adjust the inside temperature, humidity, aircleanliness, and air flow of the vehicle 100 to maintain the inside ofthe vehicle 100 pleasant. The air conditioner 131 may include at leastone vent 131 a installed in the center fascia 124 on an outer portion ofthe dashboard 122 and discharging air. In addition to the airconditioner 131, the center fascia 124 may further include an airconditioning switch 131 b, such as a button or a dial, to enable theuser to operate the air conditioner 131. Accordingly, the user such as adriver may control the air conditioner 131 by using the button disposedon the center fascia 124. Herein, the term driver is intended to includeany individual in the vehicle, whether or not the individual is actuallyoperating the vehicle.

The vehicle 100 may include various electronic devices in an inner spaceof the dashboard 122, that is, behind the center fascia 124 in which thevent 131 a of the air conditioner 131 is positioned. FIG. 2 is a blockdiagram for describing a positional relationship between some componentsof the air conditioner 131 and an integrated controller 300 with anADAS.

However, in the inner space of the dashboard 122 of the vehicle 100illustrated in FIG. 2 , other electronic devices may be furtherinstalled in addition to the air conditioner 131 and the integratedcontroller 300. For example, the integrated controller 300 may furtherinclude an additional air conditioning duct in the inner space of thedashboard 122 by branching an air conditioning duct connected to acenter console installed between a driver's seat and a passenger's seatin the air conditioner 131 and coupling the branched air conditioningduct to the upper end of the integrated controller 300.

Particularly, as illustrated in FIG. 2 , the air conditioner 131 and theintegrated controller 300 may be installed in the inner space of thedashboard 122. In FIG. 2 , components for hardwarily operating the airconditioner 131 are illustrated. In FIG. 3 , components of an airconditioning control unit 132 for softwarily operating the airconditioner 131 are illustrated in more detail. In FIG. 4 , componentsconstructing the integrated controller 300 are illustrated.

First, as illustrated in FIG. 2 , the air conditioner 131 may include anevaporator/heater 138 for discharging air circulating to the vent 131 aprovided in the center fascia 124, and include a driver 139 thatgenerates wind before the evaporator/heater 138 operates.

The driver 139 may include a fan 136 rotating by a motor 136 a, and maygenerate wind when the fan 136 is driven.

The generated wind may be provided to the vent 131 a or the integratedcontroller 300 through the evaporator/heater 138. The generated wind maypass through the vent 131 a to be supplied to the inside of the vehicle100.

More specifically, although not illustrated in the drawings, the airconditioner 131 may supply air to the integrated controller 300 becausea part of the air conditioning duct connected to the center console ofthe vehicle 100 branches to the integrated controller 300.

At this time, the supplied air may be dehumidified air when theevaporator/heater 138 operates as an evaporator, and may be hot air whenthe evaporator/heater 138 operates as a heater.

More specifically, as illustrated in FIG. 3 , the air conditioner 131may include the air conditioning switch 131 b, the air conditioningcontrol unit 132, a flow control valve 135, the evaporator/heater 138,the driver 139, and an air conditioner compressor 137. The driver 139may include the fan 136 and the motor 136 a.

The air conditioning switch 131 b, the air conditioning control unit 132and the flow control valve 135 constituting the air conditioner 131 maycommunicate with each other through a vehicle network NT.

The air conditioning control unit 132 may also communicate with theintegrated controller 300 through the vehicle network NT. Therefore, theair conditioning control unit 132 included in the air conditioner 131may generate a control signal according to a signal received from theintegrated controller 300.

The vehicle network NT may adopt a communication standard, such as MediaOriented Systems Transport (MOST) having communication speed of amaximum of 24.5 Mbps (Mega-bits per second), FlexRay havingcommunication speed of a maximum of 10 Mbps, Controller Area Network(CAN) having communication speed from 125 kbps (kilo-bits per second) to1 Mbps, and Local Interconnect Network (LIN) having communication speedof 20 kbps. The vehicle network NT may adopt one or more communicationstandards of MOST, FlexRay, CAN, and LIN.

In the air conditioner 131, the air conditioning switch 131 b may enablea driver to adjust an amount of airflow, humidity, and a temperature toa desired level, as described above.

Therefore, the air conditioner 131 may include the air conditioningcontrol unit 132 for operating the components of the air conditioner 131based on information input by the driver through the air conditioningswitch 131 b. More specifically, the air conditioning control unit 132may include a flow valve controller 133 for controlling the flow controlvalve 135 to adjust a flow rate according to a control signal, and anair conditioning controller 134 for adjusting an amount of airconditioning according to a control signal. The air conditioning controlunit 132 may generate control signals for the flow valve controller 133and the air conditioning controller 134 based on an input signalreceived from the integrated controller 300, in addition to informationreceived from the driver through the air conditioning switch 131 b.

The flow valve controller 133 may drive the flow control valve 135through the vehicle network NT, and the air conditioning controller 134may itself operate the driver 139 including the fan 136 and the motor136 a, the air conditioner compressor 137, and the evaporator/heater138.

More specifically, the flow valve controller 133 may generate a controlsignal for driving the flow control valve 135, which is a valve forcontrolling a flow rate passing through the branched air duct to theintegrated controller 300. The flow valve controller 133 may control anopening rate of the flow control valve 135 according to an amount ofheat generated by the integrated controller 300.

For example, the integrated controller 300 may transfer a measuredinside temperature to the air conditioner 131 through the vehiclenetwork NT. At this time, the integrated controller 300 may transmitinformation about a heat capacity that needs to be dissipated inconsideration of a reference temperature required for the integratedcontroller 300 to operate normally, to the air conditioner 131 throughthe vehicle network NT.

The air conditioning controller 134 of the air conditioner 131 maycalculate a total heat capacity based on the information about the heatcapacity received from the integrated controller 300 and an airconditioning setting value set by the driver through the airconditioning switch 131 b.

Also, the air conditioning controller 134 may generate a signal for anopening rate required by the flow valve controller 133 based on thecalculated total heat capacity, and transmit the generated signal forthe opening rate to the flow control valve 135 through the vehiclenetwork NT. The air conditioning controller 134 may transmit a vehicleair conditioning control signal to at least one of the driver 139, theair conditioner compressor 137, and the evaporator/heater 138.

For example, the air conditioning controller 134 may increase an openingrate of the flow control valve 135, when an amount of heat generationincreases due to continuous operations of the integrated controller 300,and when additional heat dissipation is required, the air conditioningcontroller 134 may increase an operation amount of the air conditionercompressor 137.

Also, as an example, when a heat capacity that needs to be dissipated,received from the integrated controller 300, is small, the airconditioning controller 134 may reduce an opening rate of the flowcontrol valve 135, thereby reducing cool air that is transmitted to theintegrated controller 300.

As described above with reference to FIG. 2 , the driver 139 may includethe fan 136 rotating by the motor 136 a, and when the fan 136 is driven,the air conditioner 131 may generate wind.

The generated wind may be provided to the vent 131 a or the integratedcontroller 300 through the evaporator/heater 138, and pass through thevent 131 a to be supplied to the inside of the vehicle 100.

The air conditioner compressor 137 may be a refrigerant compressor, andwhen the air conditioner compressor 137 is applied to the vehicle 100,the air conditioner compressor 137 may generally operate in the state inwhich a refrigerant and oil are mixed. That is, the air conditionercompressor 137 may convert rotation energy into reciprocating energythrough a cylinder to compress a refrigerant, to decrease a temperature,and to generate cold wind through a heat exchanger.

Therefore, for example, when wind generated through the driver 139 isgenerated as cold wind through the air conditioner compressor 137 andthen passes through the evaporator 138, the air conditioner 131 mayprovide air of low temperature and low humidity to a vehicle indoorenvironment of high temperature and high humidity in hot weather such asa summer.

The integrated controller 300, which receives air from the airconditioner 131, may have a structure as illustrated in FIG. 4 .

FIG. 4 is a side view of the integrated controller 300 according to anembodiment of the disclosure. FIG. 4 illustrates the integratedcontroller 300 as a structure for covering a plurality of printedcircuit boards (PCBs) 411 a, 411 b, and 411 c with aluminum housings 410and 414 configured with a plurality of heat dissipation fins.

The plurality of printed circuit boards 411 a, 411 b, and 411 c may beconfigured by mounting a high-performance application processor (AP) ora field-programmable gate array (FPGA) on a conventional microcontroller unit (MCU). This is because high-performance and high-speedoperations are required when sensor fusion and deep-running imagerecognition technology are applied by mounting various sensors tooperate the ADAS.

Therefore, in FIG. 4 , the first printed circuit board 411 a, the secondprinted circuit board 411 b, and the third printed circuit board 411 cmay correspond to the MCU, the AP, and the FPGA chip, respectively. Theprinted circuit boards 411 (411 a to 411 c) may be high-heatingelements, and generally designed to be in direct contact with thehousings 410 and 414. At the upper end of each printed circuit board411, a thermal grease 412 (412 a to 412 d) may be applied on boltfastening portions 415 (415 a to 415 c) connecting the housings 410 and414 to the printed circuit board 411 to improve heat transferefficiency.

That is, the thermal grease 412 (412 a to 412 d) may be provided on atleast a part of one surface of the at least one printed circuit board411 and at least a part of the surfaces of the housings 410 and 414 tobe positioned between the printed circuit board 411 and the housings 410and 414.

The housings 410 and 414 may also include a cover housing 410 and a basehousing 414.

The printed circuit board 411 may be disposed in the inside of at leastone of the cover housing 410 and the base housing 414, and the thermalgrease 412 may be provided between the printed circuit board 411 and thehousings 410 and 414.

Heat dissipation fins P41 and P42 provided on the housings 410 and 414may protrude from at least one upper surface of the cover housing 410and from at least one lower surface of the base housing 414.

The integrated controller 300 of FIG. 4 may branch the air conditioningduct connected to the center console from the air conditioner 131 andfasten the air conditioning duct to the upper end of the integratedcontroller 300 in order to increase an heat dissipation effect byapplying the heat dissipation fins P41 and P42 to the upper and lowerhousings 410 and 414. More specifically, at the upper end of theintegrated controller 300, the flow control valve 135 of the airconditioner 131 may be positioned to control an amount of air that istransmitted to the integrated controller 300. This configuration will bedescribed in detail in the following embodiment referring to FIGS. 5 and7 .

In addition, as will be described later with reference to FIG. 5 , theintegrated controller 300 may be positioned at the top of a chassisframe 310 of the vehicle 100 so that inside heat of the lower housing414 of the integrated controller 300 is transferred to the chassis frame310, and the chassis frame 310 and the integrated controller 300 may becooled by convection caused by airflow in the lower portion of thevehicle 100 when the vehicle 100 is driven.

More specifically, FIG. 5 is a schematic view for describinginteractions between an air conditioner and an integrated controlleraccording to an embodiment of the disclosure, and FIG. 6 is a flowchartillustrating a method for controlling a vehicle according to anembodiment of the disclosure. FIGS. 5 and 6 relate to an embodiment foroptimizing the heat dissipation performance of the integrated controller300 when the air conditioner 131 operates in summer.

For example, as illustrated in FIG. 5 , the integrated controller 300may be provided as a structure capable of receiving air from an airconditioning duct branched upward from the upper housing 410, and theflow control valve 135 for controlling an amount of air transmitted fromthe air conditioning duct may be located between the air conditioningduct and the integrated controller 300.

Accordingly, the flow control valve 135 may control an amount of airthat is transmitted to the integrated controller 300 according to acontrol signal from the flow valve controller 133 of the airconditioning control unit 132.

In addition, the chassis frame 310 may be positioned at the lower end ofthe integrated controller 300, and the chassis frame 310 and theintegrated controller 300 may be cooled by convection caused by airflowin the lower portion of the vehicle 100 when the vehicle 100 is driven.

At this time, the flow valve controller 133 for controlling the flowcontrol valve 135 may control an opening rate of the flow control valve135 based on an input signal input through the air conditioning switch131 b and temperature information of the integrated controller 300.

That is, FIG. 6 is a flowchart illustrating a vehicle control method fordissipating the heat of the integrated controller 300 by using the airconditioner 131 in summer.

First, the integrated controller 300 and the air conditioner 131 mountedon the vehicle 100 may start controlling the vehicle 100 according tothe embodiment of the disclosure when the vehicle 100 starts, inoperations 601 and 610.

The integrated controller 300 and the air conditioner 131 may beincluded in a separate vehicle and operate through the vehicle networkNT. As illustrated in FIG. 6 , the air conditioner 131 may receiveinformation about a heat capacity that needs to be dissipated,calculated by the integrated controller 300, from the integratedcontroller 300.

The integrated controller 300 and the air conditioner 131 may operateindependently in parallel. For convenience of description, an operationmethod of the integrated controller 300 will be first described asfollows.

When the vehicle 100 starts in operation 601, the integrated controller300 may measure an inside temperature of the integrated controller 300configured with at least one chip, in operation 602. The first printedcircuit board 411 a, the second printed circuit board 411 b, and thethird printed circuit board 411 c of the integrated controller 300configured with at least one chip may be the MCU, the AP, and the FPGAchip, respectively. When the first printed circuit board 411 a is a mainprinted circuit board, the first printed circuit board 411 a maydiagnose a chip temperature of the first printed circuit board 411 a, achip temperature of the second printed circuit board 411 b received fromthe second printed circuit board 411 b, and a chip temperature of thethird printed circuit board 411 c received from the third printedcircuit board 411 c to calculate a heat capacity A that needs to bedissipated, in consideration of a reference temperature at which theintegrated controller 300 operates normally, in operation 604. At thistime, the integrated controller 300 may determine whether heatdissipation is needed in consideration of the reference temperature atwhich the integrated controller 300 operates normally, in operation 603.Accordingly, when the integrated controller 300 determines that heatdissipation is needed (YES in operation 603), the integrated controller300 may calculate a heat capacity A that needs to be dissipated, andtransmit the calculated heat capacity A to the air conditioner 131.

Then, the air conditioner 131 may obtain an air conditioning settingvalue input by the driver through the air conditioning switch 131 b whenthe vehicle 100 starts, in operation 611. At this time, the airconditioning setting value input by the driver may include an air volumeand temperature information. In addition, the air conditioner 131 mayobtain a vehicle indoor temperature to set an air conditioning valueaccording to the air conditioning setting value, in operation 612.

The air conditioner 131, which has received the heat capacity A requiredfor heat dissipation of the integrated controller 300 from theintegrated controller 300, may calculate a total heat capacity Brequired for heat dissipation in consideration of both the airconditioning setting value and the heat capacity A, in operation 613.When the total heat capacity B is larger than a reference value which isa reference level allowing air-conditioning control with the airconditioning setting value set by the driver (YES in operation 614), theair conditioner 131 may compensate for the air conditioning settingvalue, in operation 615. For example, the air conditioner 131 maydecrease the setting temperature, and increase the air volume.

In contrast, when the total heat capacity B is smaller than thereference value which is the reference level allowing vehicle airconditioning control with the air conditioning setting value set by thedriver (NO in operation 614), the air conditioner 131 may control theflow control valve 135 to dissipate heat of the integrated controller300. That is, the integrated controller 300 may open the flow controlvalve 135.

FIGS. 5 and 6 described above correspond to an embodiment for optimizingthe heat dissipation performance of the integrated controller 300 insummer.

FIGS. 7 and 8 illustrate a method of supplying heated air to prevent thetemperature of the integrated controller 300 from falling excessively inwinter.

For example, as illustrated in FIG. 7 , which is the same as FIG. 5 ,the integrated controller 300 may be provided as a structure capable ofreceiving air from the air conditioning duct branched upward from theupper housing 410, and the flow control valve 135 for controlling anamount of air transmitted from the air conditioning duct may bepositioned between the air conditioning duct and the integratedcontroller 300.

Thus, when air transmitted from the air conditioning duct is hot wind,the integrated controller 300 may absorb heat from the hot wind passingthrough the flow control valve 135.

Accordingly, the flow control valve 135 may control an amount of airthat is transmitted to the integrated controller 300 according to acontrol signal from the flow valve controller 133 of the airconditioning control unit 132.

In addition, the chassis frame 310 may be positioned below theintegrated controller 300, and accordingly, when the vehicle 100 isdriven, heat of the chassis frame 310 and the integrated controller 300may be dissipated by convection caused by airflow in the lower portionof the vehicle 100.

At this time, the flow valve controller 133 for controlling the flowcontrol valve 135 may control an opening rate of the flow control valve135 based on an input signal input through the air conditioning switch131 b and temperature information of the integrated controller 300.

That is, FIG. 8 is a flowchart illustrating a vehicle control method forpreventing the temperature of the integrated controller 300 from fallingexcessively by using the air conditioner 131 in winter.

First, the integrated controller 300 and the air conditioner 131 mountedon the vehicle 100 may start controlling the vehicle 100 according to anembodiment of the disclosure when the vehicle 100 starts, in operations801 and 810.

The integrated controller 300 and the air conditioner 131 may beincluded in a separate vehicle and operate through the vehicle networkNT. As illustrated in FIG. 6 , the air conditioner 131 may receive avalue of a heat capacity that needs to be dissipated, calculated by theintegrated controller 300, from the integrated controller 300.

The integrated controller 300 and the air conditioner 131 may operateindependently in parallel. For convenience of description, an operationmethod of the integrated controller 300 will be first described asfollows.

When the vehicle 100 starts in operation 801, the integrated controller300 may measure an inside temperature of the integrated controller 300configured with at least one chip, in operation 802. Herein, the firstprinted circuit board 411 a, the second printed circuit board 411 b, andthe third printed circuit board 411 c of the integrated controller 300configured with at least one chip may correspond to the MCU, the AP, andthe FPGA chip, respectively. When the first printed circuit board 411 ais a main printed circuit board, the first printed circuit board 411 amay diagnose a chip temperature of the first printed circuit board 411a, a chip temperature of the second printed circuit board 411 b receivedfrom the second printed circuit board 411 b, and a chip temperature ofthe third printed circuit board 411 c received from the third printedcircuit board 411 c to calculate a heat capacity value C for heatabsorption in consideration of a reference temperature at which theintegrated controller 300 operates normally, in operation 804. At thistime, the integrated controller 300 may determine whether heatabsorption is needed, in consideration of a predetermined normaloperation temperature of the integrated controller 300 as a referencevalue, in operation 803. Accordingly, when the integrated controller 300determines that the heat absorption is needed (YES in operation 803),the integrated controller 300 may calculate the heat capacity value Cfor the heat absorption and transmit the calculated heat capacity valueC to the air conditioner 131.

Then, when the vehicle 100 starts, the air conditioner 131 may obtain anair conditioning setting value input by the driver through the airconditioning switch 131 b, in operation 811. The air conditioningsetting value input by the driver may include an air volume andtemperature information. In addition, the air conditioner 131 may obtaina vehicle indoor temperature to set an air conditioning value accordingto the air conditioning setting value, in operation 812.

The air conditioner 131 that has receives the required heat capacityvalue C of the integrated controller 300 from the integrated controller300 may calculate a total heat capacity B that needs to be dissipated,in consideration of both the air conditioning setting value and the heatcapacity value C, in operation 813. When the total heat capacity B islarger than a reference value which is a reference level allowingair-conditioning control with the air conditioning setting value set bythe driver (YES in operation 814), the air conditioner 131 maycompensate for the air conditioning setting value, in operation 815. Forexample, the air conditioner 131 may decrease the setting temperature,and increase the air volume, thereby discharging hot wind.

In contrast, when the total heat capacity B is smaller than thereference value which is the reference level allowing air conditioningcontrol with the air conditioning setting value set by the driver (NO inoperation 814), the air conditioner 131 may control the flow controlvalve 135 to dissipate heat of the integrated controller 300. That is,the integrated controller 300 may open the flow control valve 135.

That is, a case in which the integrated controller 300 is frozen inwinter so as not to operate properly may be prevented in advance, asseen from FIG. 8 .

FIG. 9 is a side view of an integrated controller according to anotherembodiment of the disclosure. In the case of an integrated controller300 illustrated in FIG. 9 , the integrated controller 300 may have astructure of covering a plurality of printed circuit boards (PCBs) 911a, 911 b and 911 c with aluminum housings 910 and 914 configured with aplurality of heat dissipation fins, like the integrated controller 300shown in FIG. 4 .

The plurality of printed circuit boards 911 a, 911 b, and 911 c may beconfigured by mounting a high performance AP or a high performance FPGAon a MCU. This is because high-performance and high-speed operations arerequired when sensor fusion and deep-running image recognitiontechnology are applied by mounting various sensors to operate the ADAS.

However, as shown in FIG. 9 , in the lower housing 914, lower ends ofthe heat dissipation fins may be flat to maximize thermal conductionwith the chassis frame 310.

As is apparent from the above description, the vehicle for reducing theheat generation of the integrated controller equipped with the ADAS, andthe method of controlling the vehicle may be provided.

Further, the vehicle for preventing the temperature of the integratedcontroller equipped with the ADAS from falling excessively, and themethod of controlling the vehicle may be provided.

Further, the integrated controller equipped with the ADAS, the ADASmounted on the vehicle, may be provided as a structure that is operablein such a way not to be sensitive to an external temperature.

It will be obvious topeople of ordinary skill in the art that the present disclosure may bepracticed in other forms than the exemplary embodiments as describedabove without changing the technical idea or essential features of thepresent disclosure.
